Jet lag could up cancer risk

London: Frequent travelling that causes jet lag could increase your risk of cancer because it tends to disturb our body clocks that are controlled by the same mechanism that causes tumours, finds a study

The findings, reported in the Daily Mail, showed that people’s internal body clocks have a major influence on cell multiplication and has the potential to prevent cancer.

“Our internal clock is in sync with external light and dark cues, and prompts people’s behaviour and activity levels,” lead author Angela Relogio from the Charite-Medical University in Berlin, was quoted as saying by Daily Mail.

“Based on our results, it seems to us that the clock is likely to act as a tumour suppressor,” Relogio added.

For the study, published in the journal PLOS Biology, the team analysed a protein known as RAS, which is inappropriately activated in around one quarter of cancerous cells, in mice.
